When I said it is worth it - I didnt mean it necessarily mean monetarily. It's worth it bc its a NA spec 83 cruiser, a piece of history of sorts. The barrier to entry of a pristine 83 is still high. This would allow you to get one and fix it up slowly. In that case it MIGHT be a good return on investment but most likely not. If you are trying to make money there are alot of ways better than flipping cruisers right now. Prices of FJ40's are down bc of a number of factors, one of which includes the influx of cruisers from South America.
If you dont care about the year, there are plenty of good non rusty fj40's that show up on CA craigslist that are driveable right now.
